Your problem is caused by hosting service's ignorance.
open_basedir should be includes the temporary directory for php uploading.
File(/var/tmp/phpWS1amx) is not within the allowed path(s): (/home/spascom:/usr/lib/php:/usr/local/lib/php:/tmp)
This means your server's php uploads /var/tmp but this directory is not in open_basedir's list.
Claim it to the administrator or move to another hosting services.
